Abstract
An apparatus for separating coarse particles from a fluid or wet stream, optionally containing fine particles, includes a frame, a screen box, means attached to the frame and to the screen box for movably suspending the screen box on the frame for vibratory motion, a pair of opposing screens which are mounted in the screen box and which allow liquids and fine particles to pass through to the bottom of the screen box to separate discharge openings associated with each screen and allows coarse particles to pass over each screen and onto a single centrally positioned discharge chute, and motor means attached to the screen box for vibrating the screen box and screens mounted thereto. The apparatus can be used for such separation operations as dewatering, desliming and wet scalping, and is especially useful for applications wherein the oversize or coarse particles constitute a major portion of the total feed.
